CVE-2024-5322Network attack vector

Authentication bypass via Entra SSO session rebinding

Published Jul 1, 2024 · Updated Aug 1, 2024

Authentication bypass in N-able N-central before 2024.3 allows remote attackers to assume authenticated sessions through Entra SSO. The Entra SSO session-binding logic rebinds an existing authenticated N-central session instead of preserving its original user association. Exposure is limited to Entra-supported deployments and grants the rebound user's access; N-able has not disclosed lower-level implementation details.
